Charlie De La Paz, 17, laughed and called his sentence a "joke" after being ordered to serve life for killing his 15 year old Girlfriend, Nikita Tang.
A passerby discovered the body of Tang lying, partially unclothed, behind the local city hall. The girl had mud and sticks shoved into her mouth and an autopsy showed there were marks on her neck.
De La Paz, who pleaded guilty after confessing to the murder, said the couple had sex, Tang had mocked him, and he had just snapped. De La Paz will be eligible for parole at age 53; if granted, he will be supervised for the rest of his life.
